Concept explainers

Capacity and Level of Service at Intersections

The term capacity is associated with transportation engineering. Capacity helps to understand how many pedestrians or vehicles can be handled by a transport facility. Level of service is also a term associated with transportation engineering. The level of service indicates the performance of the transport facility.

A rural highway has one lane in each direction. In one direction V = 300 veh/hr/ln at a railroad crossing. The barriers at this crossing are lowered to block vehicles for four minutes and 30 seconds for a train to pass. What is the probability that when the barrier is lifted, the queue has exactly nine vehicles? Assume no initial queue.
16. A bus line operates in mixed traffic and caries 4000 passengers per peak hour at an average speed of 10 mi/h. Typically each bus makes two scheduled stops per mile and is interrupted by the traffic- control system and other vehicles six times per mile. Given an average occupancy of 50 persons per bus and a 5-mi trip, calculate the number of buses needed to serve the passenger demand and the total amount of fuel consumed during a typical peak hour.
Vehicles arrived at the entrance of San Juanico Bridge in Tacloban at a rate of 180 vehicles per hour. Vehicles must stop at the tollgate where vehicles will have to pay a toll fee upon entering the bridge. It would take 15seconds per vehicle for the attendant to issue a trip ticket. Compute the traffic intensity at the bridge.
freeway with two northbound lanes is shut down because of an accident. At the time of the accident, the traffic flow rate is 1200 vehicles per hour per lane and the flow remains at this level. The capacity of the freeway is 2200 vehicles per hour per lane when not impacted by an accident. The freeway is shut down completely for 20 minutes after the accident; then one lane is opened 20 minutes after accident; and finally both lanes are opened 40 minutes after the accident. What is the total delay resulting from the accident (assuming D/D/1 queuing)?
2. There are two routes in use between Zones 1 and 2. The volume-delay functions for the two routes are as follows: V1 V2 t1 = 22 + 250 t2 = 15 + 150 where t = travel time(minutes) V = traffic volume If the total traffic volume is 6,950 vehicles per hour between the two zones, what are the traffic volumes and travel times on each of the two routes at a user-equilibrium (UE) condition?
Vehicles arrive at the carpark of an airport. Vehicles have to queue at the single entrance gate of the carpark at 9:00 AM. The arrival rate is constant at 240 veh/hr. However, between 9:00 and 9:40 AM, the parking ticket machine at the entrance works slowly due to a malfunction, and consequently, each vehicle spends 30 seconds to take the parking ticket. After 9:40 AM, the problem is solved and vehicles spend only 10 seconds at the gate to take the ticket. In how many minutes does the queue dissipate? Select one: a. 60 b. 70 c. 75 d. 80
Question. 2Propagation speed of 45 km/hr and that each toll booth takes 6 seconds to service a car.Suppose the caravan of 10 cars begins immediately in front of the first toll booth, travels 20 km to a second toll booth, then another 40 km to a third toll booth, and finally stops immediately after the third tool booth. Thus, they travel a total of 60 km. What is the total end to-end delay?
4. Two busses start at the same time towards each other from terminals A and B, 8 km apart. The time needed for the bus to travel A to B is 8 minutes, and of the second bus from B to A is 10 minutes. How much is the time needed by each bus to meet each if they travelled at their respective uniform speeds?
8.21 Three routes connect an origin and destination with performance functions t₁ = 2 +0.5x₁,₂ = 1 + x2 and 13 = 4 + 0.2x, (with f's in minutes and x's in thousands of vehicles per hour). Determine user- equilibrium flows if the total origin-to-destination demand is (a) 5000 veh/h.
The arrival times of vehicles at the ticket gate of a sports stadium may be assumed to bePoisson with a mean of 30 mi/h. It takes an average of 1.5 min for the necessary tickets to be bought for occupants of each car. (a) What is the expected length of queue at the ticket gate, not including the vehicle being served? (b) What is the probability that there are no more than 5 cars at the gate, including the vehicle being served? (c) What will be the average waiting time of a vehicle?
In this problem, assume a propagation speed of 45 km/hr and that each toll booth takes 6 seconds to service a car. Suppose the caravan of 10 cars begins immediately in front of the first toll booth, travels 20 km to a second toll booth, then another 40 km to a third toll booth, and finally stops immediately after the third tool booth. Thus, they travel a total of 60 km. What is the total endto-end delay?
